rule 1 - if the carbon chain attached to a cyclic hydrocarbon & contains equal or more number of carbon atoms present in

       cyclic ring then ring is treated as substituent ...

rule 2 - number will start in such a manner so that functional group gets least number ...

 

here in this example according to rule 2 - benzene ring is treated as substituent  &  numbering is done so that amino group(NH2) gets least number ...NH2 functional group...
